RANA PIPIENS. 81 
called Rana halecina; and this leaves the name pipiens unapplied, at least so far 
as Gmelin is concerned, 
It is next used by Schneider in his “ Historia Amphibiorum;” his whole descrip- 
tion, however, refers to the halecina of Kalm, or the Water-frog of Catesby. 
Latreille was the first who.used the specific name pipiens without synonymes, or 
reference to any author, stating only that the animal was called, in Carolina, the 
Bull-frog; his description is correct, and applicable to the Bull-frog in every 
particular but one: he speaks of a light-coloured vertebral line, which [have never 
seen in any individual of this species. 
Latreille separates it from the Rana ocellata, which he describes as a distinct 
animal, and says, furthermore, that his Rana pipiens must not be mistaken for that 
of Schneider (Gmelin), which we have seen is the Rana halecina of Kalm; 
consequently then to Latreille is due the merit of first definitely applying the 
specific name pipiens to our Bull-frog. 
It is singular that Daudin should not have followed his example, but far from it; 
he, under his Rana pipiens, gives three animals entirely distinct from each other, 
and his plate makes a fourth, for it represents an Indian animal, and not the 
American Bull-frog. 
N. B. Though Gmelin quotes Schneider, he does not quote the name he gives 
the animal.
